Baseline Traits and Infused Volumes of 500 Outpatients Hydrated After Exposure to Contrast Medium.

Description of outpatients in the intent-to-treat sample (n = 500) randomized to treatment. Groups were compared by using a chi square test for categorical variables and ANOVA for continuous variables.aχ2 = 8.553, df = 3, 2-tailed P-value. Treatment: group 1 (N-acetylcysteine plus saline; NAC), group 2 (sodium bicarbonate plus saline; NaHCO3), group 3 (N-acetylcysteine plus sodium bicarbonate plus saline; NAC+NaHCO3), group 4 (saline). Abbreviations: ACE (angiotensin-converting enzyme), ARB (angiotensin II receptor blocker), B-blocker (beta-adrenergic blocking agent), CCB (calcium channel blocker), CI-AKI (contrast-induced acute kidney injury), eGFR (MDRD) (glomerular filtration rate estimated with a Modification of Diet in Renal Disease formula), eGFR (sCys C) (glomerular filtration rate estimated with a serum cystatin C formula).Baseline Traits and Infused Volumes of 500 Outpatients Hydrated After Exposure to Contrast Medium.
